How to Handle a Lodging Rate Change or Credit in DTS When Using Non-Conventional Lodging

Rate changes and credits are normal on TDY lodging. A stay shortens. Headcount drops. A seasonal per diem adjustment alters the reimbursable ceiling. A provider issues a credit for unused nights or a corrected rate. These events occur with hotels and with non-conventional houses. The Joint Travel Regulations do not treat them differently. What matters is that the final amount claimed in the Defense Travel System matches the net official cost and that the supporting document makes the change visible.

When the lodging is a house booked as non-conventional lodging, the invoice comes from the provider rather than a hotel folio system. The same principles apply. The document must show the original expectation, the adjustment, and the net amount due. The traveler claims only that net amount for the official nights. Finance can then approve the voucher without requiring an amendment or additional explanation.

Recognizing a Rate Change Versus a Credit

A rate change alters the nightly amount for some or all of the stay. It may result from a corrected calculation, an extension into a different per diem period, or an agreed adjustment after the original booking. The final invoice should reflect the rate that actually applies to each night or group of nights.

A credit reduces the total owed without necessarily changing the underlying nightly rate. Common reasons include an early departure, a reduction in the number of travelers, or the removal of nights that fell outside the official orders. The credit appears as a line item or a clearly noted reduction so the net total is lower than the original estimate.

Both situations require the same outcome in DTS. The claimed lodging amount equals the final net figure on the invoice for the authorized TDY dates. Amounts above per diem on any night remain the traveler’s responsibility and are excluded from the claim. Personal leave nights, if any, are also excluded.

Preparing the Supporting Document

Request the final itemized invoice as soon as the change is known and before the voucher is submitted. The invoice should contain the property address, the dates of occupancy, the nightly rate or rates, any credit or adjustment with a short reason, and the net amount due. If the provider’s standard invoice does not itemize the credit clearly, a one-page schedule attached to the invoice can list the original nights, the credited nights, and the resulting total.

Do not alter the provider’s invoice. Annotations are acceptable when they simply highlight the official nights or the net reimbursable amount, but the original figures must remain legible. Finance offices expect source documents. A recreated or heavily edited receipt creates questions that delay approval.

If two different rates apply because of a seasonal per diem change, the invoice or attachment should separate the nights before the change from the nights after the change. The traveler then claims the allowable amount under each cap. This keeps the voucher aligned with the published rates for those specific dates.

Entering the Adjusted Amount in DTS

Create or edit the lodging entry so the dates match the official nights actually used and the amount matches the net total on the final invoice. Upload the invoice and any short explanatory schedule. If the system requires a receipt for each segment, attach the same document to the relevant entry and note that it covers the adjusted stay.

Add a brief remark when the adjustment is not self-explanatory. Examples include “Credit for early departure on [date], net amount claimed” or “Rate adjusted for seasonal per diem change effective [date].” The remark does not replace the invoice. It simply points the reviewer to the reason the final figure differs from the original authorization estimate.

Government Travel Card charges should be reconciled to the net amount before submission. If the card was charged the original higher amount, the credit should already have reduced the charge or the traveler should have paid the difference back. The amount claimed and the amount charged need to align, or the difference must be explained and resolved.

Common Rate-Change and Credit Scenarios

An early departure produces a credit for the unused nights. The final invoice shows the original reservation reduced by those nights. The traveler claims only the nights stayed. No further calculation is required beyond confirming the net total.

A headcount reduction on a team house generates a credit tied to the departed travelers. The invoice reflects the lower occupancy or the credited portion. Each remaining traveler claims the adjusted share or the invoice is claimed at the new net total according to how the unit handles shared lodging. The document must make the reduction obvious.

A mid-stay seasonal per diem drop means later nights are capped at the new lower rate. The property may have charged a flat rate. The traveler claims up to the applicable cap for each period and pays any excess personally. The supporting schedule shows the split so the claimed total is clearly inside both limits.

A provider-issued rate correction lowers the nightly amount after booking. The revised invoice replaces the original estimate. The traveler claims the corrected net amount. The original confirmation can be retained in the travel file but does not need to be uploaded if the final invoice is complete.

Avoiding the Most Frequent Errors

Claiming the original estimated amount after a credit has been issued is the most common mistake. The voucher then exceeds the receipt and is reduced or returned. Always claim the final net figure.

Submitting a summary confirmation instead of the final invoice leaves the credit or rate change undocumented. The final itemized document is the one that belongs in DTS.

Failing to separate personal nights or excess-over-per-diem amounts causes an improper claim. Those costs stay with the traveler and do not appear in the reimbursable total.

Waiting until voucher submission to request the adjusted invoice increases the chance of a mismatch. Obtain the final document as soon as the change occurs.

Coordination With the Lodging Provider

Notify the provider as soon as you know a rate change or credit will be needed. Early notice allows the final invoice to be prepared correctly rather than corrected later. For non-conventional lodging managed as an official reservation, the provider can issue the credit against the unit booking without involving personal cards or consumer-platform penalties.

Confirm the net amount and the reason for the adjustment in writing before the traveler submits the voucher. A simple email confirmation that matches the invoice gives an additional reference if finance has questions. Keep that confirmation with the travel record.

If the change affects only some travelers on a team stay, ensure the invoice or the unit’s internal assignment list shows who is covered by the remaining nights. This prevents one traveler from claiming nights that belonged to someone who departed.

Frequently Asked Questions

Can a house invoice show a credit the same way a hotel folio does?


Yes. The final invoice should itemize or clearly note the reduction and state the net amount due. That net amount is what is entered in DTS.

What if the rate changes because of a seasonal per diem adjustment?


Claim only up to the cap in effect on each night. Use the invoice or an attached schedule to show the nights under each rate.

Do I upload both the original confirmation and the final invoice?


The final invoice is required. The original confirmation can be kept in the unit file but is not normally needed in DTS if the final document is complete and shows the adjustment.

Who receives the money when a credit is issued?


On a company-booked non-conventional reservation the credit reduces the amount the unit owes. It does not create a personal refund the traveler must track.

What remark should I add in DTS?


A single sentence that states the reason and confirms the net amount is claimed. Example: “Early departure credit applied, net lodging claimed per final invoice.”

Keeping the Claim Supportable

A lodging rate change or credit does not make non-conventional lodging difficult to process in DTS. It requires the same documentation standard applied to any adjusted hotel stay. The final invoice shows the net official cost. The amount entered in DTS matches that net cost. A short explanation connects the two when the reason is not obvious. Finance can approve the voucher because the record is complete.

Units that use houses instead of hotels for mission reasons can handle these adjustments inside the existing process. The provider issues a clear final document. The traveler claims the correct net amount. The JTR and DTS requirements remain satisfied.

If your TDY may involve date changes, headcount shifts, or the need for a clean credit or rate adjustment on the final invoice, note that possibility when you send the trip request to www.9lineagency.com. The courses of action and the invoicing process can be set up to produce the itemized record DTS expects. The lodging stays compliant. The voucher stays supportable. The mission does not have to pause for paperwork.
